摘要：

[GRAPHICS] A pentiptycene-bispyrenyl system (1) has been synthesized and investigated as a fluorescent chemosensor for metal ions, A novel blue shift along with an intensity enhancement of the pyrene excimer emission is observed for 1 in the presence of Cu2+. Such a new signal transduction mode of pyrene probes results from the formation of a static pyrene excimer that has very different characteristics from its dynamic counterpart.
